He is in the break-up with an INFJ girl (not tested or confirmed but I strongly feel she is - the INJ are 100%, the F I would say 95%).
This situation is very strange to me, and I cannot relate at all.
She is 26 (I am 24, to put into perspective I am 27 so she is closer to me than to him in age).
She is of course as an INFJ, very intelligent, strong character, I would say she never seems at ease with me, but I am not sure if that is her personality in general, or just her reaction to me. She is pretty and elegant, not my style personally (tall and thin figure, I prefer a curvy look), but certainly, would be considered an attractive and intelligent young girl.
Also she is Spanish speaking and similair in he appearance to my mother, who is also refined, ENFJ, Spanish speaking etc. So you can see where am going - at a glance I even confused her with my mother a few times before, as they even dress similarly, and both do the same job!
My brother and this girl for the past 10 months or so have spent pretty much every day together. He has slept at her house ever night, she moved across the city to live just 5 minutes from us, she got a job close to our home. When my brother was away on holiday for a few months she was worried if a day went by without him writing. They have almost never been apart, they never miss a call, they do everything together, even socializing.
I noticed she is also very jealous of other girls who have shown any inteest in my broher at any point, even very unattractive looking ones who are 35 (a nice person though).
Then suddenly, my brother came home yesterday, and said to my mother that his GF had said to him, that she was worried thy are "too different" and she was worried about the future, and they should break up. Apparently they have been talking about this for 3 days. There was apaprently no argument, just "little things" they disagreed on. He then went to her house that night because she wanted him to spend the night there, and now he has gone to spend "one last night" there tonight. When asked if they were getting back together, he said "maybe".
This to me is very fucked up. I have ended relationships before, but I have never gone from such an intense relationship, to such a seemingly "cold" break up over no particular argument. It seems very strange she could go from that level of depending on him, to ending it.
That is all the information I have at hand, could any INFJ shed any light on what might be going on?
My theory is maybe they are both too strong characters with very high standards for themselves and others, and neither one ever gives way to the other one on the "little things" so it's like a constant ego struggle. But this really is just conjecture, because there does not seem to have been any warning of this coming, in fact, until 2 days ago I would have told you they were basically a married couple.
